Darn! I installed the dictionary as per the same link you posted, but it didn't work. It has to be a problem with the csv file or the command I'm using with penelope, because I managed to successfully install 2 other English dictionaries found on this site (WordNet and Websters)
Anyone have any suggestions? The csv file I created has 2 columns, no header (first column has the word, second has the definition). Here is the link to the csv file in case I messed that up:
